I started learning about sublimation printers through the website http://sublimationweb.com, which sells a variety of sublimation printers. They also sell specialty cutters, papers, and other useful products for printing.
The company is based in Italy and offers export of their products to other countries. Above all, the company provides customer service to prospective buyers; anyone interested in their products should contact them to discuss the best options based on what you need to print. They also offer two-year warranties on all their products. Their site is an interesting introduction to the world of sublimation printing.
